SUB TRANSMISSION OF AGRICULTURE VEHICLE

摘要

A sub-transmission for an agriculture vehicle is disclosed. According to an embodiment of the present invention, a sub-transmission for an agriculture vehicle includes: an input shaft directly connected to an output shaft of a main transmission; an intermediate shaft constantly engaged with the input shaft to be rotated; a drive shaft configured to output transmission power; a front-end hollow shaft and a rear-end hollow shaft rotatably provided on the drive shaft, wherein a spline gear in the middle of the drive shaft is interposed between the front-end hollow shaft and the rear-end hollow shaft; change gears provided on the drive shaft, the front-end hollow shaft, and the rear-end hollow shaft to be engaged with each other to make a pair; and a shifter disposed on the spline gear to linearly move between the front-end hollow shaft and the rear-end hollow shaft. Thus, the gears may be shifted and put in neutral in multiple stages by the linear movement of the shifter which linearly moves between the front-end hollow shaft and the rear-end hollow shaft.
